I use to use ASC for years and though it worked well. I've run it on all OS from XP on up to 10. I uninstalled in the past year because I got sick of it constantly trying to install it's other programs. Plus it was taking up so much of my background space. I felt hounded and just didn't want to have to babysit it all the time anymore. Yes, be careful when you install it. Make sure you do advance install. If you don't pay attention you will be downloading several PUPs that you agree to downloading because you didn't read or pay attention! Since uninstalling my pcs actually run faster and I don't have to be hounded with updates/install this program or that. If Iobit would not make ASC so intrusive, I'd love to use it again. There are other wonderful programs out there that don't need to run constantly or have to constantly try to get you to update/install their programs. Google Iobit and Advanced System Care. There are so many out there that do not recommend it. But there are a few favorable reviews as well. Bottom line: use at your own risk. There are good valid reasons why Malwarebytes, Avira and others block you from having.

In my Opinion:
With reference to comment #3 &2, it is particularly rare that I uninstall a program because of odd and untrustworthy operational characteristics....

I had this installed some time ago (no license restrictions), yet I removed it.
I also once used IO bit's antivirus. I pulled that out too.

IO bit has had a long history of software development standards that appear to be "less than ethical".

Lets face it guys and gals, we simply never know what any program is doing under the hood.
There are NO software tools telling us if, or when, any of our data is being siphoned off. Perhaps there should be !!! (note for s/w developers!)

No, I am NOT suggesting IO bit is doing that or has ever done that.
However, the presence of law suit(s) simply says to me, stand clear.

I've had the same problem with Malware Bytes flagging Advanced System Care as a PUP. I like ASC and think it does an excellent job but don't use it anymore because 1) the conflict between MB and ASC and 2) ASC is a heavyweight in taking up space. I use CCleaner, Malware Bytes and Win Utilities now to keep my computer clean

I don´t recommend this app, may be it works fine, but it installs more application I didn´t choose to install . App from same company. I didn´t any change at settings, but it installed some applications ...
